What swift_package_test does on XcodeBazelMCP
AI agents invoke swift_package_test to trigger actions in XcodeBazelMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why swift_package_test is rated High
This tool runs tests, which involves executing arbitrary code in a Swift package. Test execution can trigger side effects, consume resources, modify state, or run malicious code if the package is compromised. It is categorized as Execute rather than Read because it actively runs code, not merely queries data.
From the tool's definition 'Run tests in a Swift package' — actively executes test code within a Swift package environment
Attacks that exploit this kind of access
The rule that runs swift_package_test safely
PolicyLayer is an MCP gateway: it sits between your AI agents and XcodeBazelMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For swift_package_test, this is the rule to start with:
swift_package_test stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect XcodeBazelMCP, apply this rule, and every swift_package_test call is checked against it from then on.
Questions about swift_package_test
Run tests in a Swift package using. It is categorised as a Execute tool in the XcodeBazelMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for swift_package_test: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches XcodeBazelMCP. Nothing to install.
swift_package_test is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the swift_package_test rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for swift_package_test. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
swift_package_test is provided by the XcodeBazel MCP server (xcodebazelmcp/xcodebazelmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
